Ironwood State Prison (ISP) is a state prison located south of Interstate 10, in a detached section of Blythe, California, that lies west of the main portion of the city.

It is located in eastern Riverside County, California, adjacent to Chuckawalla Valley State Prison.

Parts of the Level III facilities have been converted to Sensitive Needs Yard (SNY) housing, and one of the Level III housing units has been converted to an Administrative Segregation Unit.
